What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.00189 |
| Opus 5.5 | $0.00019 | $0.00076 |
| Sonnet 5.5 | $0.00009 | $0.00038 |
| Haiku 4.5 | $0.00005 | $0.00019 |
Grade A, and why
matryca-github scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Matryca GitHub workflow
Read these canonical rules completely before acting:
.cursor/rules/08-github-workflow-standards.mdc.cursor/rules/09-github-identity-marco-porcellato.mdc.cursor/rules/10-tooling-static-analysis-policy.mdc
Do not perform remote mutations without explicit user authorization.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

matryca-github is a skill published in the GitHub repository MarcoPorcellato/matryca-plumber (100 stars, last pushed yesterday), licensed Apache-2.0. It adds 47 tokens to every session and 189 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
